摘要翻译：
不同的特征对特定的学习问题有不同的相关性。一些特征不太相关；虽然有些很重要。一个算法可以根据专家意见或先验学习给出特征重要性的知识，而不是使用特征选择来选择最相关的特征。如果学习者考虑到特征的重要性，学习可以更快更准确。相关辅助神经网络(CANN)就是这样一种算法。CANN将特征重要性视为目标属性与特征之间的相关系数。CANN对常规前馈神经网络进行了修正，使其既能拟合相关值，又能拟合训练数据。实验结果表明，CANN算法比采用两步特征选择方法和常规学习算法更快、更准确。

英文摘要：
  Different features have different relevance to a particular learning problem. Some features are less relevant; while some very important. Instead of selecting the most relevant features using feature selection, an algorithm can be given this knowledge of feature importance based on expert opinion or prior learning. Learning can be faster and more accurate if learners take feature importance into account. Correlation aided Neural Networks (CANN) is presented which is such an algorithm. CANN treats feature importance as the correlation coefficient between the target attribute and the features. CANN modifies normal feed-forward Neural Network to fit both correlation values and training data. Empirical evaluation shows that CANN is faster and more accurate than applying the two step approach of feature selection and then using normal learning algorithms.
